No, I didn’t wait until the last sentence to say the main idea of that posting. In fact, I made it a point to state it right away in the title: Our apologies for the Forum’s momentary outage on March 27, 2013. You really couldn’t do it earlier than that. In short notices of this kind, don’t think of paragraph development the way it’s formally taught. The title is integral to the message, and the body of the notice would just be wasting the reader’s time if it were to repeat in the first sentence what the title has already stated very clearly. In short, we shouldn’t expect notices of this type to have all the bells and whistles of an essay or some other exposition.
